PECIE'ICATION forming part of Letters Patent No. 328,969, dated October27, 1885.

Application filed April 30, 1885. Serial No. 163,974. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, HENRY L. PEOR, a citizen of the United States,residing at Newark, in the county of Licking and State of Ohio, haveinvented certain new and useful Improvements iu Draw-Bars; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to the mode of connecting the draw-heads anddraft-rods of railway-cars.

My improvement consists of the combination of a T-headed draft-rod witha drawhead the hollow shank of which is so channeled internally that theT-head of the draftrod can be inserted through the rear end of thedraw-head and be made tointerlock therewith after giving it aquarter-turn.

In order that my invention may be clearly understood, I have illustratedin the annexed drawings and will proceed to describe a practical formthereof.

Figure l represents a vertical longitudinal section of so much of arailway-car as will snfiice to show the nature and application of myinvention. Fig. 2 represents a vertical longitudinal section of adraw-head, showing the T-headed end of the draft-rod in elevation. Fig.Srepresents a cross-section of the draw-head, taken in the plane ofbroken line a: :v of Fig. 2. Fig. 4 represents a cross-section of thedraw-head, taken in the plane of broken line y y of Fig. 2. Fig. 5represents a crosssection of the draft-rod. Fig. 6 represents ahorizontal section of the draw-head. Fig. l is drawn on a smaller scalethan the other figures. y

The same letters of reference indicate identical parts in all thefigures.

The hollow shank of the draw-head A is internally channeled by fourlongitudinal grooves, a a and aa, and a transverse groove, a2, whichunites adjacent grooves a and a at the inner end of the hollow shank.The

grooves c o; lie in the horizontal axial plane of the draw-head andextend to and are open at the outer end of the hollow shank, while thegrooves a a lie in the Vertical aXial plane of the draw-head and areclosed by stout webs a3 a3 at the outer end of the hollow shank. Thegrooves a a form a horizontal way or channel, the grooves a a a verticalor crossway or channel, and groove a2 forms a connecting way or channel.

The draft-rod Bis constructed, at the end which is to enter the hollowshank of the draw-head, with a so-called T-head, b, as clearly shown inFig. 5. The head bis adapted to enter the horizontal channel of thehollow draw-head shank, and to be turned through the connecting-channela2 into the cross-channel, withdrawal from which at the outer end of theshank is prevented by the webs a3 a3.

It will be observed that the above-described combination of a draw-headhaving an internally cross-channeled hollow shank and a T- headdraft-rod greatly facilitates the application or removal of draw-head ordraft-rod. It also affords a very safe connection, which cannot beaccidentally severed without smashing the parts, for when once properlyapplied to a car the T-head of the draft-rod cannot reach theconnecting-channel a2 at the extreme inner end ofthe hollow shank. Yeton disconnecting the outer end of the draft-rod from the car suchdraft-rod may be pushed into the hollow draw-head shank up to theconnecting-channel a2 and turned so as to permit its withdrawal throughthe horizontal channel. g

I claim as my inventionl. The combination, substantially as before setforth, of a draw-head having ahollow internally cross-channeled shankand a T- headed draft-rod.

2. AdraW-head the hollow shank of which is internally cross-channeled,substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
